Hi Fabián Andres Huamani Rojas,

I understand how scary this looks, but as the Q&A Assist has stated, this is a Windows account / sign‑in configuration issue. This can happen when work/school sign‑in components are broken or out of sync. Here is how you can attempt to fix it:

1 - Sign in without using the PIN

• On the login screen, click Sign‑in options (Opciones de inicio de sesión)
• Choose Password and sign in using your Microsoft account password
• Once in, open Settings > Accounts > Sign‑in options > Remove PIN
• Still in Accounts > Access work or school > Disconnect all listed
• Restart the PC > go back to Sign‑in options > Add new PIN.

2 - If that doesn't work, remove the corrupted PIN from WinRE

• On the lock screen, hold Shift and select Restart (bottom right)
• Keep holding Shift until you get to Windows Recovery Environment:
  • If it doesn’t work, you need to force shutting down PC 3 times.
  • Each device has a different way to enter WinRE, check to ensure.
• Once in WinRE, go to Troubleshoot > Advanced options > Command Prompt
• Run these commands one by one (press Enter after each):
  • diskpart
  • list vol Look for the volume that contains the folder called Windows (often C:)
  • exit
  • cd /d C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft (replace C: if it's different)
  • dir
  • ren Ngc Ngc.old
• Then restart the PC > try signing in with password > follow the Solution #1

Once the PIN is rebuilt and any orphaned work/school entry is removed, the message should not come back. If any of the above fails, reply back with the exact error message or text and I’ll help look further for more solutions if needed.

The purple “Sign in required” window and the Windows logon screen with error 0x80284001 are legitimate Microsoft/Windows messages, not a virus. They indicate:

• Windows thinks the device is (or was) connected to a work or school account and is asking to re‑authenticate that account.
• Windows Hello PIN sign‑in is temporarily broken for the account, so the stored PIN cannot be used and must be reset.

Because of this, normal PIN sign‑in fails, but the PC itself is not being locked by malware.

To get back in and fix it, use only built‑in Windows options on the sign‑in screen:

1. On the PIN screen, select Opciones de inicio de sesión (Sign‑in options).
2. Choose another available method such as:
   • Password for the same account, or
   • Picture password, or
   • Any other method shown.
3. After signing in successfully, change or reset the Windows sign‑in method:
   • If using a Microsoft account password, follow the guidance in Change or reset your Windows password or Forgot your Microsoft account password.
   • If the local profile is damaged, follow Fix a corrupted user profile.
4. Once signed in and the account is working again, set up a new PIN from Settings → Accounts → Sign‑in options.

If none of the sign‑in options work, use the official troubleshooting paths for Windows sign‑in problems listed below to reset the PIN, password, or repair the profile.
